HEADLIGHT.

Specification of Letters Patent.

Patented Aug. 27, 1907.

Application filed November 28, 1 906. $erial No. 345,496-

To all whom it may concern:

Be it known that I, DAVID MCMICKEN TONER, a citizen of the UnitedStates, residing at Beechwood, in the county of Cameron and State ofPennsylvania, have inventedanew and useful Improvement in Headlights, ofwhich the following is a specification.

This invention relates to headlights and more particularly to headlightsfor locomotives; the object being to provide a headlight so constructedthat the beam of light from the lamp on the reflector will be held onthe track automatically while the locomotive is rounding a curve, and atthesame time the lamp will be held perfectly horizontal, so that it willnot be deflected when the road is rough.

Another object of my invention is to provide a refiector which can bereadily attached to the ordinary head-light now in general use.

Another object of my invention is to provide very novel means forpreventing the pendulum weight from shifting suddenly so as to preventthe platform carrying the lamp from being jerked or jolted.

Withithese objectsin view, the invention consists in the novel featuresof construction, combination and arrangement of parts hereinafter fullydescribed and pointed out in the claims.

In the drawings forming a part of this specification Figure l is alongitudinal vertical sectional view through my improved headlight apart being broken away. Fig. 2 is a transverse vertical sectional viewof the headlight. Fig. 3 is a top plan View of the platform of theheadlight removed. Fig. 4 is a perspective view of the arm carrying thependulum and a portion of the piston rod. Fig. 5 is a detail perspectiveview of a portion of the lower platform showing the stud and journalblock. Fig. 6 is a similar view of the top platform and journal blockstud showing the manner of supporting the journal block. Fig. 7 is aperspective view of the arm and a portion of the platform supportinglinks. Fig. 8 is a sectional view through the platform. Fig. 9 is avertical section through one of the cylinders.

In the drawings A indicates the casing of the headlight which is of theordinary shape and construction, and is provided with the usual glasscovered front door A.

Arranged in the rear of the casing adjacent each side are uprights Bconnected together at their upper ends by a cross bar B in which iscentrally secured a forwardly projecting bolt 0 onwhich is mounted thecentured ends of the piston rods F having piston-heads F at their lowerends provided with openings F which work in cylinders G adapted to befilled with alcohol provided with oppositely disposed outwardlyprojecting lugs G adjacent their lower ends which are mounted inapertures formed in the uprights B and uprights H arranged in the casingin alinement with the uprights B.

Mounted on the bolt 0 is the centrally apertured cross-arm I which isprovided with a depending stem I having a bifurcated end I adapted tofit over a screw-bolt E secured in the front face of the pendulum so asto swing the arm I with the arm D. The ends of the arm I carry bolts 1on which the apertured ends .I of the links J are pivotally mounted, thelower ends of which are connected to eyes I secured in the platform Kadjacent its rear edge, so that the platform will be tilted when theweight swings, so as to hold it perfectly horizontal. A stud pin Kprojects out centrally from the front edge of the platform K and ismounted in a journal block L provided with a bolt L which is pivotallymounted in the bottom of the casing. A forked arm K projects outcentrally from the rear of the platform in which the depending pin E ofthe pendulum is adapted to fit so that when the pendulum swings, theplatform will be carried with it. A circular grooved track K is securedon the top of the platform K in which are arranged balls K on which ismounted the grooved circular track M of the lamp supporting platform M,the two being pivotally connected together centrally by a pivotbolt N.Projecting out centrally from the platform M is a stud-pin M mounted ina journal-block 0 provided with a bolt 0 which is pivotally mounted in across-bar P secured to the sides ofthe casing. A reflector Q is mountedon brackets Q secured on the platform M under which a lamp is adapted tobe ar ranged.

The operation is as follows:-As soon as the 1000- motive reaches a curvein the road-bed, it of course being understood that the inner rail islower than the outer rail, its center of gravity is shifted from the center of the road-bed towards the inner rail causing the pendulum to alsoseek the center of gravity which will swing the arm D causing the pistonto work through the alcohol in the cylinder which will gradually allowthe pendulum to reach the center of gravity without any sudden jolt, atthe same time the arm I is swung by the bolt carried by the pendulumworking in the bifurcated stem raising the platform K into a horizontalposition. When the pendulum swings over the pin in the bottom working inthe bifurcated arm of the platform K, causing the platform K to turn inthe direction as shown by the arrows V, shifting the centrally pivotedpart of the platform to W and causes the platform M to turn in a reversedirection as shown by the arrow X thereby causing the beam of light tofollow the track as the locomotive rounds a curve.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:
